During the thirteenth century, a group of people who worshiped Satan and called themselves the Knights Templar were cruelly put to death by the villagers after being captured while participating in a ritual. In the final moments of their deaths, the Knights make a solemn oath to rise from their graves and haunt both the adjacent settlement and the forest. Several centuries later, in a post-apocalyptic future, a man and his daughter fight both the Undead Knights and a group led by a crazed preacher in an effort to stay alive. Their enemies include both groups.
